` GREASE-CUP.

Specification of Letters Patent.

Patented Dec. 14, 1920.

Application mea February 14, 1920. serial No. 358,796.

To all whom t may concern.'

Be it known that I, LESTER R. FoGG, a citizen of the United States, residin at Quincy, in the county of Norfolk and tate of Massachusetts, have invented new and useful improvements in Grease-Cups, of which the following is a specification.

rihis invention relates to improvements in grease cups.

It is an object of the invention to provide a grease cup which will be non-leakable and which may be filled with grease and manipulated to feed said grease without soiling the hands and without the danger of mixing dirt with said grease, by virtue of the fact that the absence of grease upon the outside of the device eliminates toa great extent, the tendency7 of the dust and grit to stick thereto and accidentally get into the cup While refilling. Y y

t is also an object of the invention'to so construct the device that when` the same is filled with grease thecover may be attached Y and locked' inposition andthe grease fed as desired by rotating all the necessary parts in a similar direction, and when the cup re-V quires refilling the said parts may all be rotated-in a reverse direction in order that the device -may be opened and the cup refilled.

It is still further an object of the invention to so join the, various parts that have screw threaded engagement with each other together, that said parts can not become separated during the ordinary operation of the device, thereby eliminating the possibility of cross-threading and also of mutilating the threads because of carelessness or haste in assembling.

The invention consists in the combination and arrangement of parts whereby the above objects and certain other objects hereinafter appearing may be attained as set forthv in the following speciication and particularly pointed out in the claims'thereof.

lReferring to the drawings:

. Figure 1 is a side elevation of a grease cup embodying my invention, a portion of the cover thereof being broken away to more clearly illustrate portions 'of the device therebehind.

Fig. 2 is a vertical section as taken on the line 2 2 of Fig. 1.

Fig. 3 is a plan view of the cylindrical casing.

FigA is a side elevation ofthe cylindrical` casing as viewed from the rear of Fig. 1.

Fig. 5 lis an underneath plan View of the cover together with the various parts mount@ ed thereon.

Like numerals refer to like parts throughV outthe several views of the drawings.

InV the drawings, 1 represents a stationary member which is provided with a down- -wardly extending stem 2 adapted to be attached by means of a threaded portion 3 to any device requiring lubrication. The stationary member 1 is provided at its upper end with a cup-shaped cavity 4 which has an outlet passage 5 leading therefrom and extending downwardly through the stem 2.

The stem 2 is also provided with a heX- agonal portion 6 which may be engaged by a wrench when attaching or removing the grease cup from any device to which it may be secured.

Rotatably mounted upon the upper portion of the stationary member 1 is a cylindrical casing 7 which constitutes the main body portion of the grease cup. The interior of the cylindrical casing 7 is screw threaded at 8 to fit a corresponding screw thread 9 provided upon the exterior of the upper portion of the stationary member 1. After the cylindrical casing 7 has been attached to the stationary member l a plurality of pins 10 are inserted in said casing at the lower end thereof, the said pins projecting inwardly a suflicient distance to engage the stationary member 1 and thereafter prevent said casing 7 and stationary member 1 from becoming detached from each other. The interior of the casing 7 coperates with the cavity 4 of the stationary member 1 in forming a grease chamber 11.

Formed in the periphery of the casing 7 near the upper end thereof is a groove 12 which extends nearly around the circumference thereof, one end of said groove constituting a stop 13. A plurality of short vertical grooves 14 extend from a top edge 15 of the casing 7 downwardly and connect thereof. A; luralit` of pins 18 and'ajsmall lo y screw 29 are fast-to the cover 17 and pro'ect inwardly a short distance therefrom. he pins 18 and screw 29 are furthermore spaced to register with the vertical grooves 14 and recesses 16 of the casing 7. .Located within the cover 17 is an auxiliary cover V19 which,

whenthe cover 17 is detached from the casing 7, is forced by a spring-20`again'st the upper side of the pins 18y and screw 29 which act as stops to retain said auxiliary cover within said cover. The pins 18 are permanently attached to the cover 17; the screw 29, however, may be removed from said cover andwhen so removedmakes it possible for the auxiliary cover 19. 'and spring 2O to be removed from within said cover. The auxiliary cover 19 consists of an upper disk 21 and a lower disk 22, of shorter diameter within the disk 21, between which is inserted a klayer of iiexible material 23 composed of cork or vother suitable substance which will not deteriorate from contactwitn grease. The disks 21 and 22 and "layer 23 are firmly secured together by a centrally located rivet 24. Y

The cover 17 is attached to the casing 7 by alining` the pins l18 and screw .29 withy the grooves 14 and then forcing' the cover downwardly, theA auxiliary cover 19 yielding as it engages .the top edge 15 of the ing 7. As' the auxiliary cover yields, the pins 18 and screw 29 will pass downwardly through the grooves 14 until they contact with the bottom edge of the circumferential groove 12, whereupon Athe cover 17 is rotated toward the right, the pins 18 and screw 29 traveling along the groove 12 untilr one of said pins or the screw 29 engages the stop 13 vwhereupon all of the pins 18 and thej screwv 29 will register with the recesses 16 and will be forced upwardly therein by the 'pressure of the auxiliary cover 19 against the tope'dge 15 of the casing 7.

rEhe cover 17 may now be locked in this position by means ofy a thumb-screwl which is centrally located in said cover and which may be rotated until it engages the rivet 24 of the auxiliary 4cover 19 thereby forcing the layer ofcork 23 against the top I edge 15 of the cylindrical casing 7 and also preventing the auxiliary cover from yielding when pressure is applied downwardly to said cover and thereby Vpreventingthe pins 18 andscrew 29 from becoming'disengaged from their respective recesses 16. A spring washer 26 isinserted between the top of the cover 17 and head 27 of the vhandling thereof.

the friction between said parts and prevent the screw 25 from loosening when theV cover y grease, the cover-.17. whichis securely locked to the casing 7 by the screwY 25, is grasped and rotated toward the left until the pins 10 underside of the stationarymernber 1- and prevent further rotation of' said casing. The thumb-screw 25 is ythen rotated toward the left until it also is prevented vfrom rotating 'by the pin 28 contacting with the 90 underside of the cover 17. The cover'17 is then pressed downwardly and the'k auxiliary cover 19 which is now being pressed against the top Y'edge 15 of the casing 7 by the spring thumb-screw 25 and is adapted to increase i i Vat the lower end of the casing 7 engage' the 20, will yield against the tension of said vspring'allowing lthe pins 18 and screw 29 to "be disengaged fromthe recesses 16, whereupon the cover117 may be rotated toward the left until the pins 18 and screw 29 yaline with the grooves 14 thereby allowingsaid y cover to be'lift'ed away from the casing 7.

After inserting grease kwithin the chamber 11the cover isfagain applied to the casing 7 slots 14 andV forcing said cover downwardly against the tension of the spring 2() until said pins and screw contact with the bottom edge of the circumferential groove 12.` The cover is then rotated toward the right until one of the pins 18 or the screw 29 engages y the stop 13 whereupon the said pins and screw are' forced into the recesses 16. Thev thumb-screw 25 Vis'then rotated toward the right (until it contacts Vwiththe auxiliary cover 19 and forces the same against the top edgel 15 of the casing 7 thereby vsimultaneously locking the cover 17V to the casing 7 vby alining the pins 18 and screw 29 with the grease downwardly from thechamber 11 through the passage. It will be noted'that in opening thegrease cup preparatory to filling, the various parts are all rotated toward the left'- and in 'closing the cup and feeding the'gr'ease the parts are all rotated toward the right. This simplifies and quickens each operation. DuringY thenormal operation of the device it is impossible to separate any. parts which have screw vthreaded engagement with each other,
